This demonstration tire also tested to have lower rolling resistance when compared to the reference tire, made with traditional materials. Lower rolling resistance means this demonstration tire has the potential to offer better fuel savings and carbon footprint reduction.
In addition, after announcing the capability to demonstrate a 70% sustainable-material tire in
Bringing a 90% sustainable-material tire to market will require further collaboration with the company's supply base to identify the scale necessary for these innovative materials to produce that specific tire at high volumes.
'We continue to make progress toward our goal of introducing the first 100% sustainable-material tire in the industry by 2030,' said
90%
This 90% sustainable-material demonstration tire includes 17 featured ingredients across 12 different components, including:
Carbon black, which is included in tires for compound reinforcement and to help increase their life, has traditionally been made by burning various types of petroleum products.
The use of soybean oil in this demonstration tire helps keep the tire's rubber compound pliable in changing temperatures. Soybean oil is a bio-based resource that helps to reduce
Silica is an ingredient often used in tires to help improve grip and reduce fuel consumption. This demonstration tire includes a high-quality silica produced from rice husk waste residue (RHA silica), a byproduct of rice processing that is often discarded and put into landfills.
Polyester is recycled from post-consumer bottles by reverting the polyester into base chemicals and reforming them into technical grade polyester used in tire cords.
Resins are used to help improve and enhance tire traction performance. In this demonstration tire, traditional petroleum-based resins are replaced with bio-renewable pine tree resins.
Bead wire and steel cords provide reinforcement in the structure of a radial tire. This demonstration tire uses bead wire and steel cord from steel with high-recycled content, which is produced using the electric arc furnace (EAF) process. The utilization of the EAF process allows for steel to be produced with reduced energy use and higher recycled content. The EAF process has the potential for lower greenhouse gas emissions in comparison with steel produced using a blast furnace.
ISCC certified mass balance polymers from bio- and bio-circular feedstock are also included in this tire.
The shift to sustainable materials is evident in some of
*A sustainable material is defined as a bio-based/renewable, recycled material or one that may be produced using or contributing to other sustainable practices for resource conservation and/or emissions reductions including mass-balance materials.
**The 90% sustainable-material tire has been developed as a demonstration tire, which means
